RESERVOlR-FOUNTAlN-PEN FILLER.

SPECIFICATION forming part of Letters Patent No. 722,508, dated March10, 1903. Application filed August 12, 1902. Serial No. 119,380. (Nomodel.)

In order that those skilled in the art to which my invention appertainsmay understand, construct, and use my invention, I will proceed todescribe it, referring to the drawings herewith, in which- I Figure 1 isa longitudinal central section of one form of my invention. Fig. 2 is atop view of Fig. 1. Fig. 3 is another form of my invention inlongitudinal central section on line a; y of 4; and Fig. 4 is an endView of Fig. 3 looking from the bottom end upward to show the roundupper end and wedgeshaped lower end of the reservoir A, the sides beingpinched together at the bottom and held by a clip K. Fig. 5 is anotherform of my invention shown in longitudinal central section; and Fig. 6is a top view of same, showing the discharge or filling cone solid withthe reservoir and the open lower end of the reservoir A closed by ascrew-cap G. All these forms are refillable and compressible.

In all the figures the same reference-letters indicate like orequivalent parts.

A is the ink-reservoir.

B is the threaded head-piece, conical in form at its upper end and atits top coming to a fine point for a purpose disclosed farther on inthis specification.

C is a screw-cap having packing I in its upper end and screwed uponhead-piece B at E to seal the apparatus.

D is a fine hole running longitudinally through the head-piece B,through which the ink is to be discharged in a minute stream for fillinga fountain-pen. The conical sides or surfaces of the head-piece Bapproach at its top closely to the edges of the fine hole D, so that thetop of the cone is practically merely a needle-point at J.

Head-pieces B in Figs. 1 and 3 are screwed into the upper end ofreservoir A at F, so that the said reservoir can be refilled by removingthe head-piece B-and closed again by replacing it. In Fig. 5 the lowerend of the reservoir A is opened for refilling and again closed byremoving the cap G and again replacing it by screwing it onto reservoirA at screw H. In Figs. 1 and 5 the reservoirAis shown as cylindrical,While in Fig. 3 it is cylindrical at its upper end and wedge-shaped atits bottom, the sides being held together tightly by a clip K.

The effect of making the top of the cone on head-piece B a fine point isthat the drop of ink which will remain upon the point J or upper end ofthe fine hole D will not run down the sides of the cone, but will beheld fixed at the said point a period and be drawn again into thereservoir A through hole D by the inrush of air which occurs after thedischarge of ink from it.

The reservoir A is to be made of celluloid or equivalent material, whichhas a slight flexibility and resiliency, so that to discharge ink fromthe reservoir a pressure by the fingers upon its outer surface causesthe sides to yield inwardly and the ink to flow outwardly when cap 0 isremoved and the apparatus is turned upon its side to fill a pen. Uponremoving the pressure the sides return to their original form and air issucked into the reservoir to supply the place of the discharged ink, sothat this operation may be repeated until all the ink is discharged. To

refill, the head B or the cap G is removed, re-

spectively.

I am not aware that reservoirs for ink have ever been made of materialhaving the qualities of celluloid, as above set forth.

Having now fully described my invention and the manner in which I haveembodied it, what I claim as new and as my invention, and desire tosecure by Letters Patent, is

As an article of manufacture, an ink-reservoir and fountain-pen fillerconsisting of an ink-chamber A of flexible material. as celluloid; aconical head-piece B having a longitudinal central perforation D ofminute size, and threaded to receive a closing cap 0 and packing I, saidink-chamber A being constructed as shown and described with a threadtwosubscribing witnesses, this 8th day of Aued end to receive a threadedclosing-piece, gust, 1902. whereby the chamber A may be opened forrefilling and closed to retain ink,substantia1ly MAY THOMAS HORN 5 asspecified. Witnesses:

In testimony whereof I have signed my JAMES M. HICKS,

name to this specification, in the presence of FREDERIG E. SNUDLE.
